    TargetTwo more Gravity-1 flights before 2027

    Gravity-1 Y3 lofted eight Qianfan networking satellites and one EUHT technology-test satellite from waters off Shanghai at 06:00 Beijing time on September 16, 2026 (22:00 UTC September 15), the vehicle's fourth success and its first giant-LEO constellation networking mission. Orienspace told CCTV it wants two more batch missions before 2027 after that Q3 flight. Gravity-2 has not flown, so Gravity-1 remains the company's only operational launcher.

  1. Orienspace's Gravity-1 flies first commercial sea launch

    Orienspace's solid-fuel Gravity-1 rocket lifted off from a service ship in the East China Sea off Shanghai on July 22, 2026, its third flight and first fully commercial mission. The launch deployed nine satellites, including six Dongpo satellites for the Huantian constellation, and set a new national record for combined payload weight delivered into orbit by a Chinese private rocket, marking China's first far-sea commercial launch.
